A former student of mechanics wishes to weigh him- self but has access only to a scale A with capacity lim- ited to 100 lb and a small 20-lb spring dynamometer B. With the rig shown he discovers that when he ex- erts a pull on the rope so that B registers 19 lb, the scale A reads 67 lb. What is his correct weight? B A
